2 heyets-sheet 2 Filed May 2? 3mm/Wem@ lill While thestandards 2 are referred to as being channeled, they are provided with intermediate longitudinal ribs 10, which divide the standards into parallel guides o r channels 11.

`Mounted in bearings ofthe upper and lower parts of the standards 2 are shafts 12 and 13, and carried thereby are sprockets 1l and 15, which are engaged by the endless sprocket chains 16. These chains travel upon the outer faces of the outer flanges of the standards, and pivoted detachably on the chains at spaced intervalsare panels 16a. Each panel comprises an angle iron frame 17', lthe upper portion of which has axially aligned pintles or journals 18. These journals or pintles 18 are mounted detachably on the chains 16. By mounting the journals or pintles' 18 detachably on lthe chains, it is Ypossible to re-move Vthe panels, for replace- -vment by others, or-to permit the advertisement on each panel to beV removed, and others attached. The advertisement may be painted on a sheet metal plate carried by the fra-ine 17, or may be supplied on a cloth or .piece of paper or any .other suita-bleIna-terial,

which in turn may be pasted at the edges to the sheet metal panels of the frames 17. The sheet metal panels 19 ofthe Jframes 17 are riveted or otherwise secured to therframes, which are constructed of 'angle iron. The lower portion vof. each frame 17, which carries a panel, is provided with axially aligned vlugs 20. These lugs operate in the guides 11 of the standards2, so asto prevent the wind or--other'weather disturbances from vibrating the'pa-nels or frames, which would prevent the advertisement .from Abeing easily read. w l

The arms 18 ofthe panels. or frames, during their travel are upon the outer faces of thek vflanges of the channeled standards, whereas the lugs 2O are within the guides 11, thereby- ,holding the frames. or panels in slightly .inwardly inclined and downward positions, in order to .permit the radvertiseinents upon the panelstobe seen from below much easier than if the .panels lshould be hung straight or perpendicular. The arms 18 always remainon top and the lugs 20 at ik,the bottoms.

In order to permit. the arms 18 to pas-s the flanges of the channeled standards, vthe side lflanges of the standards are Vcut away at their upper and lower portions` as shown at 21y and 22. -Riveted to .the upper and lowerV parts of the outer flanges 23 of the vstandards at diagonal opposite portions of i vthe openings 22 are springs 24, with which the arms18 of the panels vor frames engage,

v,and then pass, byforcing the free ends of 4. the springs open... Y

vThe central flange or rib .10 of each channeled standard is cut away at its upper and lower portions, to permit of the disposition Macnee of the upper and lower shafts 12 and 13, which carry the sprockets 14. and 15. The central flange or rib 10 at its upper and lower portions below the cut away portions 26 is additionally cut away'to provide the 'openings or passages 28and 29. The central flange adjacent the lower portion of' theY `opening or passage 28 has riveted or otherwise secured thereto as at 30 a leaf spring 31, which closes the passage or opening 28.

lThe central flange 10 of each'standard adjacent the upper part of the passage or opening 28 has an extensionv 32, which extends downwardly in an inclined direction, and has its lower end edge immediately adjacent or secured at'33 to one of the side flanges of the standard, so that when the panels or frames areascending, the lower lugs of the frames or panels contact with the extension (which constitutes aV switch), so that the lower lug 20f may pass through the ypassage j thereto in any suitable manner, and is extended upwardly and .inclined toward 4one of the side flanges .of the standard. @The opening 29 has an extension 86 connected upper edge ofthis extension 3'6 (which constitutes a switch)V is located adjacentto or secured to one of the side flanges v.of the standard, so that as the lower. lug,V 20 descends inl its channel or guide, it will bev deflectedy by the extension` or switch 36 into the opposite 'guide ory channel. 1n passing into this opposite guide or channel., the' lug 2O I will pass thespring 35. bypushingjits free 'end to one side." After the. lug 2O .passesthe free endof the spring 35, it will assumea position sufiiciently below the opening or passage 29, to permit the lug 20 to ascend. From the foregoing it is obvious howfthe arms 18 shift from the exterior of one ofthe side flanges of each standard to the' exterior l j of the opposite side flange. Alsofit is, obvious how the lugs 2O are shifted'from one guide or channel of each standardv when ascendingv` to the vopposite guide. or channel,

Vwhen descending. It will be'iioted thatin this way the panels, orframes are 'main-` tained in slightly inclined positions,}`soV as to enable the advertisements thereon tobe easily read from below, and at anangle to the endless carrier. 1V. The lower shaftv 13 carries a. spur gear k37,`l with which va pinion 38 engages.Y This pinion'is carried by a motor shaft 39 'of a motor 40,1 for imparting revolu-ble move- Feb. 27, 31923.
